Get a list of currently-connected audio recording devices.
Defined in <SDL3/SDL_audio.h>
int *count); SDL_AudioDeviceID * SDL_GetAudioRecordingDevices(
int * | count | a pointer filled in with the number of devices returned, may be NULL. |
(SDL_AudioDeviceID *) Returns a 0 terminated array of device instance IDs, or NULL on failure; call SDL_GetError() for more information. This should be freed with SDL_free() when it is no longer needed.
This returns of list of available devices that record audio, like a microphone ("recording" devices). If you want devices that play sound, perhaps to speakers or headphones ("playback" devices), use SDL_GetAudioPlaybackDevices() instead.
This only returns a list of physical devices; it will not have any device IDs returned by SDL_OpenAudioDevice().
If this function returns NULL, to signify an error, *count
will be set to zero.
It is safe to call this function from any thread.
This function is available since SDL 3.0.0.
